IMPROVENIBNT 1H BQTTOIMS FOR WASHJBOILERS A ND SIMILAR VESSELS.

The Schedule referred to in these Latter! Patent and making part of the lame To all whom it may concern Be it known that I, Gnonoa H. HAZBLTQN, of the city and county of Philadelphia, and State of Pennsylvania, have made a new and useful Improvement in Tin-coated Bottoms for Wash-Boilers; and I hereby declare the iolhnving to be a full and exact description of the same.

in the mannliwtnre of metal bottoms for \\l.Sll-bOll' era, a sheet of uni-tel, such as tin plate orshect-iron, is pro. ed in snitabledios, was to ive itthe proper form.

Thio operation of pressing strains the metal at those points where the form is most changed, and at these points a corrosive action is easily set) up, which frequently destroys the bottom.

In latcnt No. 44,309, lSSilud to me, and dated September 20, 156-2, described a process of preventing tin; injurious ell'ects lii\(:l '1'i0 result from stamping; the said prowess consisting in coating the bottom, al

ter stamping, with a suitable alloy not easily affected by the usual influences to which wash-boilers are subjected. I

My present invention is a modification of that invention, and consists of-a timeoatcd bottom for washuoilers.

The mode oi mannfaetnriugjhis bottom is substantially the same as that described in the patent above i mentioned. After the bottom has been made into the proper form by stampin g or pressing in dies, it coated with tin by the ordinary process of tin plat-mg, well known top ia is skilled in the art-- boiler bottom much cheaper than sheet copper, and,

Them-w manufacture herein described, a bottom for ash-boilers and similar vessels, formed by stamping or pressing in dies a sheet of metal, and then covering it with a coat (.f (in, substantially as described.
